The bulb container of this known bulb has a shape suitable for being provided with various coatings, so that a bulb is always suitable for each of the various applications. A particularly important application is as a reflector lamp, which is the second part of the lamp envelope with a mirror coating.
and a third part. The purpose of this bulb is to provide a light beam with a high luminous flux and high luminous intensity at the beam center.
前述の電球の電球容器は光源として螺旋状白熱体用に設
計されたもので、その白熱体は最大直径部近傍にそれを
横切って配置され、電球の対称軸のまわりにまかれてい
る。The bulb envelope of the above-mentioned light bulb is designed for a spiral incandescent body as a light source, which incandescent body is placed near its largest diameter and across it, and is distributed around the axis of symmetry of the bulb.
本発明の目的はビーム中心でより高輝度な光束とより高
輝度な強度を備えた光ビームの得られる冒頭に記載した
種類の反射電球を提供せんとするものである。The object of the invention is to provide a reflector lamp of the type mentioned at the outset, which provides a light beam with a brighter luminous flux and a brighter intensity in the beam center.

ものである。DISCLOSURE OF THE INVENTION In order to achieve this object, a light bulb of the type mentioned at the outset according to the invention is provided, the light source of which is arranged on an axis and extends on either side of said maximum diameter. It is characterized by:
前述の公知の電球の電球容器は複数の放物線状分枝部の
焦点を通る、対称軸を横切る平面に少なくともこれらの

部のいずれか一方の側に延在する時には、ビームのより
高い輝度光束とビーム中心のより高い輝度強度が得られ
るという意外性があった。加えて、光ビームはより大き
な一様性があった。The bulb envelope of the above-mentioned known light bulb is specifically designed to incorporate an incandescent body in a plane passing through the foci of the plurality of parabolic branches and transverse to the axis of symmetry, coinciding at least in part with these foci. However, it was surprising that a higher brightness flux of the beam and a higher brightness intensity at the center of the beam were obtained when the light source was placed on the axis and extended to either side of its maximum diameter. In addition, the light beam had greater uniformity.
光源の軸上位置は白熱体が光源を形成するのに適切であ
るのみならず、高圧ガス放電、例えば高圧ナトリウム蒸
気放電の放電通路が電球容器の軸上に延在することを意
味している。The axial position of the light source means that not only is the incandescent body suitable for forming the light source, but also that the discharge path of a high-pressure gas discharge, for example a high-pressure sodium vapor discharge, extends on the axis of the bulb envelope. .
